Patent GB-850817-A (GB)
Title: Improvements relating to the oxidation of aromatic hydrocarbons
IPC: C07C51/31
Filed: 1957-01-02
Abstract: A process for the vapour phase fluidised catalytic oxidation of aromatic hydrocarbons to quinones and/or acid anhydrides comprises pretreating the aromatic hydrocarbon by known means to reduce the sulphur content thereof to below 0,1% by weight and then oxidising the treated aromatic hydrocarbon by means of an oxidising gas such as air or oxygen to quinones and/or acid anhydrides by passage through a vanadium pentoxide-silica-potassium pyrosulphate oxidation catalyst at a temperature from about 330 DEG C. to about 370 DEG C.  The hydrocarbon may be pretreated for example with metallic sodium or with anhydrous aluminium chloride when the sulphur content is generally reduced to about 0,02-0,06%.  The hydrocarbon is then vapourised and passed together with the oxidising gas to the bottom of the fluidised catalyst bed and the product vapours are withdrawn from the top of the bed.  A diagram of a suitable reactor is given. A suitable catalyst is a V2O5-SiO2-K2S2O7 catalyst promoted with oxides of cerium and/or silver such as that described in Specification 702,616.  The sulphur-removal before oxidation is said to reduce the falling-off of yield in the continuous process which is observed when hydrocarbons containing sulphur impurities, e.g. naphthalene containing thionaphthene, are used.  In examples naphthalene and anthracene are pretreated with sodium or aluminium chloride to reduce the sulphur-content and are then oxidised to phthalic anhydride, naphthaquinone and maleic anhydride and to anthraquinone respectively.  Comparative runs are also described. The process is also said to be applicable to the conversion of xylene to phthalic anhydride and tolualdehyde and of benzene to maleic anhydride.

Filed: 1972-01-05
Abstract: 1360574 Portable stills; distillation of water A LOWI JNR 5 Jan 1972 417/72 Heading B1B Liquid such as water is distilled in a portable still comprising a heat-conductive central flue 14 for hot gases and an annular channel 25 wherein the liquid is boiled, the bubbles being disrupted by coil-spring 49 so that only vapour passes through opening 54 into condensation chamber 55 which is provided with fins 56 between which atmospheric air circulates. The condensate is withdrawn from chamber 55 through opening 60. The hot liquid, separated from the vapour by spring 49, flows down the section on the outside of baffle 43 to reservoir 30 which comprises a member 36 of foamed plastics material, e.g. polypropylene. Reference 59 indicates the normal liquid-level in the still. The liquid passes from member 36 through openings 31 into channel 25. Baffle 43 may be made of metal, nylon or molded polypropylene. Turbulent flow of the hot gases rising in flue 14 is ensured by fins 15, 16 and plugs 17, 18, 19.

Title: Data processing systems
IPC: G06F15/17
Filed: 1967-01-04
Abstract: 1,113,081. Data processing systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. 4 Jan., 1967 [13 Jan., 1966], No. 445/67. Heading G4A. A channel unit for linking a processor and a peripheral device can respond to the processor to initiate operations by the peripheral device and contains conditional branching means which can respond to the peripheral device to initiate a new operation by the peripheral device. A processor communicates with peripheral (input/output and storage) devices via a channel unit and control units assigned to respective groups of peripheral devices. Such communication is controlled by a series of channel command words, one of which may be selected from the processor main storage by a channel address word selected by the processor main programme. A channel command word may control a peripheral device and, where neoessary, specify the initial main storage address to supply or receive data communicated to or from the peripheral device, as well as the number of bytes to be transferred. When a channel command word has been executed, it may cause the command word in the next consecutive address to be executed (" command chaining "), and so on. In this case, if two particular status signals from the peripheral device (one of them " device end ") are on, and the other status signals from the device are off, the next command word is obtained from the next address but one, instead. As a further possibility, a command word may be included to specify the address of the next command word. Thus a " loop " of command words may be followed repetitively until the peripheral device provides the two status signals mentioned, when the loop is exited from. Such a loop may be used for associative searching in a peripheral storage device, exit from the loop being required on a match being obtained. Flag bits in the channel command words are provided for various purposes, including " command chaining " (above) and causing an input/output interrupt of the processor. Two systems as in the preceding paragraph may be provided, each of the two channels being able to select a channel-to-channeladapter, common to both systems, as if it were one of the peripheral control units mentioned, thus enabling communication between the two processors to take place.

Steering and balancing.-In means for operating control surfaces, such as ailerons, which comprise a lever fulcrummed upon the control surface to be operated about an axis which is skewed in relation to the pivotal axis of the control surface, a rotatable member serves not only to impart motion to the free end of the lever, but to constrain the said free end to move substantially in a cylindrical surface. As shown in Fig. 2 a triangular lever 10 comprises a fulcrum rod 11 and stays 12, 13 terminating at their point of intersection in a ball 14. The rod 11 is secured by bearings 15, 16 to the leading edge of an aileron 17 and set at an acute angle to the pivotal axis AA thereof.
